So does Rectangle. I'm using it right now on a 49" U/W, with this Firefox window on the right-hand third, VSCode in the center third, and Discord in the top-left 6th, and Dune (2021) playing in IINA in the bottom-left 6th :-) All tied to global keyboard shortcuts too. Free, open source, and does exactly what you've asked for.
